Question

- Write short notes of the following :

(a) Finkelstein reaction (b) Rosenmund reduction

(c) Etard reaction (d) Cannizzaro’s reaction​

Answer 1

Explanation:

It is an organic reaction that uses an alkyl halide exchange into another alkyl halide through a reaction wherein the metal halide salt is used. ... The classic Finkelstein reaction involves the process of an alkyl bromide or an alkyl chloride into an alkyl iodide which is treated with a sodium iodide solution in acetone.

Rosenmund reduction is a hydrogenation process in which an acyl chloride is selectively reduced to an aldehyde. The reaction was named after Karl Wilhelm Rosenmund, who first reported it in 1918.

Answer 2

Answer:

Hello mate

Explanation:

1. Finkelstein reaction:-

The Finkelstein reaction is a Substitution Nucleophilic Bimolecular reaction (S_{N}2 Reaction) involves the exchange of halogen atom. It is an organic reaction that uses an alkyl halide exchange into another alkyl halide through a reaction wherein the metal halide salt is used.

2. Rosenmund reduction:-

Rosenmund reduction is a hydrogenation process in which an acyl chloride is selectively reduced to an aldehyde. The reaction was named after Karl Wilhelm Rosenmund, who first reported it in 1918.

3. Etard reaction :-

The Étard reaction is a chemical reaction that involves the direct oxidation of an aromatic or heterocyclic bound methyl group to an aldehyde using chromyl chloride. For example, toluene can be oxidized to benzaldehyde. It is named for the French chemist Alexandre Léon Étard.

4. Cannizzaro’s reaction:-

Cannizzaro reaction, named after its discoverer Stanislao Cannizzaro, is a chemical reaction that involves the base-induced disproportionation of two molecules of a non-enolizable aldehyde to give a primary alcohol and a carboxylic acid.
